In DNA and RNA, what “codes for amino acids”?
Stels [109]

Answer:

DNA: Three nucleotides encode an amino acid. Proteins are built from a basic set of 20 amino acids, but there are only four bases. Simple calculations show that a minimum of three bases is required to encode at least 20 amino acids.

RNA: You can think of the sequences of bases in the coding strand of DNA or in messenger RNA as coded instructions for building protein chains out of amino acids. There are 20 amino acids used in making proteins, but only four different bases to be used to code for them. Obviously one base can't code for one amino acid.

True or false: dark energy is a "repulsive force"​
lorasvet [3.4K]

Answer: True

Explanation: Dark energy is the name given to the mysterious force that is accelerating the rate at which our universe is expanding. ... Some repulsive force is pulling the universe apart and this force was dubbed “dark energy”. Riess and Livio describe the three main hypotheses to explain the nature of dark energy. The leading theory to explain the accelerating expansion is the existence of a hypothetical repulsive force called dark energy. ... "Usually this repulsion is ascribed to a mysterious dark energy that would uniformly permeate the cosmos, but nobody knows what it is nor why it behaves this way," Villata said in an email. Dark energy is believed to be responsible for the expansion of the universe, counteracting gravity, and is considered to be the fifth force acting on matter, after gravity, the electromagnetic force, and the strong and weak nuclear forces.
